You've got LEDs on both modules, Yes?
Well, use them!
Make them blink whenever they 'receive a message' or whatever.
Forget about a specific message format for now, just get the things to recognize data in general.
And again, lose the SEROUT debug messages, make the LEDs blink or something.

Unless of course your TX and RX lines are backwards or something...

1. I would put a 1 second pause to Master at initial startup (no pause to slave)
2. I would also make a minor modification as below:

Instead of HSEROUT ["S0"] I would use HSEROUT ["XYZ","0"]

and then
instead of hserin 10,MAIN,[WAIT ("S"),DATARECEIVED] ' Looking for "S0"

I would use HSERIN 10,MAIN,[WAIT ("XYZ"),DATARECEIVED] ' Looking for "0"

Where is the interrupt routine? I see if rcif in the early code and it is now missing,
look at this thread especially posts 8, 16.
